The Banded Elm Bark Beetle, Scolytus schevyrewi Semenov (Coleoptera, Curculionidae, Scolytinae) in North America: a taxonomic review and modifications to the Wood (1982) key to the species of Scolytus Geoffroy in North and Central America
In 2003, an Asian bark beetle, Scolytus schevyrewi Semenov (Coleoptera: Curculionidae: Scolytinae), the banded elm bark beetle, was detected for the first time in North America. This paper modifies the Wood (1982) key to the species of Scolytus Geoffroy to enable identification of Scolytus schevyrewi in North and Central America. Variation of diagnostic characters in Scolytus schevyrewi is disc...
متن کاملCharacterization of two non-native invasive bark beetles, Scolytus schevyrewi and Scolytus multistriatus (Coleoptera: Curculionidae: Scolytinae)
Scolytus schevyrewi Semenov, the banded elm bark beetle, and S. multistriatus Marsham, the smaller European elm bark beetle, are morphologically similar. Reliance on adult external morphological characters for identification can be problematic because of wide withinspecies variability and the need for good-quality specimens. The inability to identify developmental stages can also hamper early-d...
متن کاملSemiochemical-mediated flight strategies of two invasive elm bark beetles: a potential factor in competitive displacement.
A seven-state survey showed that the recently detected invasive Asian banded elm bark beetle, Scolytus schevyrewi Semenov, was abundant in areas of Colorado and Wyoming, whereas the long-established European elm bark beetle, S. multistriatus (Marsham), was not as abundant. In one of a series of studies to evaluate whether S. schevyrewi is competitively displacing S. multistriatus in their North...

متن کاملTarsonemid mites (Acari, Heterostigmatina) found in association with bark beetles (Insecta, Curculionidae, Scolytinae) in Iran
* Correspondence: [email protected] Bark beetles (Coleoptera: Curculionidae: Scolytinae) are one of the most important pests of woody plants, with immense economic impact, attacking unthrifty, broken, over-mature, dying, or, rarely, even healthy hosts (Wood, 1982). Among bark beetle species, the larger European elm beetle, Scolytus scolytus (Fabricius, 1775), the smaller European elm beetle, ...
